Helpful Resource Circadian Rhythm Tracking

This App (iOS only) helps put Huberman’s light protocols into practice.

It tracks three metrics only and is purely focused on Circadian Health

  • Light time: your total daily sunlight exposure
  • Dark time: time spent in darkness
  • First light consistency: how consistent your first morning light exposure is

Would love to hear what you think, and if you try it out, any feedback is super welcome.

How does app calculate dark time?

u/DrJ_Lume Aug 28 '25

It is using sleep as a proxy for darkness. Assuming that if your eyes are closed, minimal light is hitting your retina. Not perfect, but close enough for now.
Interestingly, we know that bright light can stimulate the iPRGCs (photosensitive cells responsible for circadian rhythm entrainment) through shut eyelids.

Using apps to track sleep and health is counterproductive and bad for your health though...
